Description

Technical Field

[0001] This utility model relates to the technical field of welding and fixing devices, specifically a multi-diameter rapid adaptation welding and fixing device. Background Technology

[0002] In the field of pipeline welding technology, pipelines need to be fixed and limited in position by welding fixing devices to facilitate subsequent welding operations.

[0003] Traditional welding fixing devices are typically designed for specific pipe diameters, using electric push rods to move movable clamps closer to the base. Clamping and positioning are achieved by using clamps with curvature adapted to the pipe. However, traditional clamping mechanisms lack effective radial guide rail adjustment. When dealing with pipes of different diameters, the entire set of clamps must be replaced or the clamp models must be changed manually in a cumbersome manner. This not only leads to long downtime and increased labor costs but also makes it difficult to guarantee concentricity and axial parallelism when multiple pipes are joined. Traditional clamping tables mostly adopt an integral structure, lacking a modular mechanism, resulting in high maintenance costs and poor flexibility. To address the shortcomings of existing technologies, this invention provides a multi-diameter rapid-adaptation welding fixing device to solve the above problems. Utility Model Content

A pair of movable and adjustable first adjustment platforms mounted on the base allow for adjustment of the distance between two sets of welded pipes. By setting V-shaped pipe clamping platforms on the fixed and movable clamping seats, along with a symmetrically adjustable second adjustment platform, adaptive clamping for pipes of different diameters is achieved. The detachable connection between the pipe clamping platforms and the second adjustment platform facilitates rapid replacement of the pipe clamping platforms according to working conditions, forming a modular function, improving the device's applicability, and also making maintenance convenient and cost-effective.

[0008] Preferably, a lateral support rod is fixedly connected to the movable clamp, and a support tube for limiting the lateral support rod is fixedly connected to the clamp bracket.

[0009] Preferably, a rubber block is fixedly connected to the pipe clamping platform.

[0010] Preferably, both the fixed clamp and the movable clamp are rotatably connected to a second bidirectional screw that is threadedly connected to the second adjusting table.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This embodiment discloses a multi-diameter rapid adaptation welding and fixing device, according to the appendix. Figure 1 To be continued Figure 6 As shown, the device includes a base 1 and a pair of movable and adjustable first adjustment platforms 2 on the base 1. A clamping bracket 3 is fixedly connected to the first adjustment platform 2. The clamping bracket 3 is provided with a fixed clamping seat 4 and a movable clamping seat 5 whose position can be adjusted. Both the fixed clamping seat 4 and the movable clamping seat 5 are provided with a pair of pipe clamping platforms 6 arranged in a "V" shape. Both the fixed clamping seat 4 and the movable clamping seat 5 are provided with a second adjustment platform 7 whose position can be adjusted symmetrically. The second adjustment platform 7 is used to support the pipe clamping platform 6. The pipe clamping platform 6 is detachably connected to the second adjustment platform 7.

[0019] According to the appendix Figure 1 and attached Figure 2As shown, a motor body 11 is fixedly connected to the base 1. A first bidirectional screw 12 is provided at the output end of the motor body 11. The first bidirectional screw 12 is threadedly connected to the first adjusting platform 2. The motor body 11 drives the first bidirectional screw 12 to rotate, causing the first adjusting platform 2 to move synchronously towards or away from each other on the base 1, thereby adjusting the distance between the two clamping supports 3. This allows the two sets of pipe openings to be welded to move closer or further apart, facilitating welding heating operations. Furthermore, an electric push rod 31 is fixedly connected to the clamping support 3. A movable clamp 5 is fixedly connected to the output end of the electric push rod 31. The extension and retraction of the electric push rod 31 drives the movable clamp 5 to move, achieving coordinated clamping or loosening of the pipe with the fixed clamp 4.

[0020] According to the appendix Figure 3 As shown, a lateral support rod 32 is fixedly connected to the movable clamp 5, and a support tube 33 for limiting the lateral support rod 32 is fixedly connected to the clamp bracket 3. The lateral support rod 32 slides within the support tube 33, ensuring the stability and straightness of the movable clamp 5 during movement and preventing deflection. Furthermore, a rubber block 61 is fixedly connected to the pipe clamping platform 6. The rubber block 61 provides flexible contact, increasing friction with the pipe surface while preventing scratches on the pipe.

[0021] According to the appendix Figure 4 and attached Figure 5 As shown, both the fixed clamp 4 and the movable clamp 5 are rotatably connected to a second bidirectional screw 71 threadedly connected to the second adjusting platform 7. The second bidirectional screw 71 is used to adjust the distance between the two sets of second adjusting platforms 7, thereby adjusting the distance between the pipe clamping platforms 6 to accommodate different types of pipes. By rotating the second bidirectional screw 71, the second adjusting platform 7 moves symmetrically, changing the size of the "V"-shaped opening to accommodate pipes of different diameters. Furthermore, a locking block 62 is fixedly connected to the pipe clamping platform 6, and a limiting groove 72 adapted to the locking block 62 is provided on the second adjusting platform 7. Inside the limiting groove 72, there is a retractable baffle 8 for limiting the locking block 62. The baffle 8 is slidably connected inside the second adjusting platform 7 and fixedly connected to a movable block 81. A spring 82 is fixedly connected between the movable block 81 and the second adjusting platform 7. The spring 82 provides elastic force to automatically reset the baffle 8. When the locking block 62 is inserted into the limiting groove 72, the baffle 8 is compressed and springs back, realizing the quick installation and locking of the pipe clamping platform 6, which is convenient for replacement or maintenance.

[0022] According to the appendix Figure 1 To be continued Figure 6 As shown, the device, through multi-stage adjustment of the first adjustment platform 2 and the second adjustment platform 7, enables rapid adaptation of the pipeline in the length and diameter directions. The coordinated action of the fixed clamp 4 and the movable clamp 5 ensures that the pipeline remains stably aligned during the welding process.

[0023] According to the appendix Figure 2 To be continued Figure 6 As shown, the "V"-shaped design of the pipe clamping platform 6, combined with the symmetrical adjustment of the second adjusting platform 7, can adapt to different pipe diameters, and the rubber block 61 enhances the compatibility and safety of the clamping.

[0024] According to the appendix Figure 1 To be continued Figure 6 As shown, it is particularly important to emphasize that the electric control of the motor body 11 and the electric push rod 31 realizes the automation and precision of the adjustment, reducing the intensity of manual operation; the structure of the baffle 8 and the spring 82 ensures the reliable fixation and convenient disassembly of the pipe clamping table 6, improving the flexibility of the device.

[0025] According to the appendix Figure 1 To be continued Figure 6 As shown, it is particularly important to emphasize that the cooperation between the lateral support rod 32 and the support tube 33 ensures the rigid support of the movable clamp 5 during movement, avoids vibration or displacement caused by load, and ensures welding accuracy.

[0026] Example 1: This example uses adjusting the pipe clamp as an example, combined with the attached... Figure 1 To be continued Figure 6 Detailed explanation of the workflow: The workflow is as follows: First, place the pipe between the fixed clamp 4 and the movable clamp 5 on the pipe clamping platform 6. According to the pipe diameter, rotate the second bidirectional screw 71 to adjust the spacing of the second adjusting platform 7 so that the "V" opening of the pipe clamping platform 6 is adapted to the pipe diameter. Next, start the electric push rod 31 to push the movable clamp 5 towards the fixed clamp 4 until the pipe is clamped. The lateral support rod 32 slides in the support tube 33 to ensure stability. Then, according to the spacing required for pipe heating and welding, start the motor body 11 to drive the first bidirectional screw 12 to rotate, so that the first adjusting platform 2 moves. Adjust the spacing of the clamp bracket 3 to the appropriate position and perform the welding operation. The rubber block 61 prevents the pipe from sliding and being damaged.

[0027] Example 2: This example uses the replacement of the pipe clamping platform 6 as an example, combined with the attached... Figure 4 To be continued Figure 6 Detailed explanation of the workflow: The workflow is as follows: When the pipe clamping platform 6 needs to be replaced or maintained, manually pull the baffle 8 to compress the spring 82, causing the baffle 8 to retract into the second adjusting platform 7 and release the limit on the locking block 62; then, remove the pipe clamping platform 6 from the limiting groove 72 and replace it with a new pipe clamping platform 6; release the baffle 8, the spring 82 pushes the baffle 8 to reset, automatically locking the locking block 62, and the installation is completed; the whole process does not require tools, realizing quick disassembly and assembly.
